INCANDESCENT VAPOR-LAMP.

SEECIFICATION formingpart of Letters Patent No. 728,672, dated May 19, 1903.

Application filed May 2,1901- Serial No. 58.425. (No model- To all whom it may concern:

Be it known that 1, JOHN B. CHRISTIAN, a citizen of the United States of America, and a resident of Chicago, in the county of Cook 5 and State of Illinois, have invented certain new and useful Improvements in Incandescent Vapor-Lamps, of which the following is a specification.

The present invention relates to that class IQ of Vapor-lamps in which the bowl or font and the vapor-generator are permanently connected together as a single structure, and the burner and harp or other support of the lamp are similarly connected together as another single structure, which separate structures are detachably connected together in order to permit of the ready removal of the font and generator for the convenient refilling of suohfont. 2c The object of the present improvement is to provide a simple and efficient construction and arrangement of the parts in which a simple and effective connection of the parts is effected in a safe and substantial manner, the alinement of the vapor-generator with the commingling-tube attained in an easy and certain manner, and which in addition permits of a rapid and convenient removal and replacement of the parts in the operation of refilling the font, all as will hereinafter more fully appear and be more particularly pointed out in the claims. I attain such objects by the construction and formation of parts illustrated in the accompanying draw- 5 ings, in which- Figure 1 is a side elevation of a vapor-lamp embodying my present invention; Fig. 2, an

enlarged fragmentary sectional elevation illustrating the details of construction of the o present invention.

Similar numerals of reference indicate like parts in the different views.

Referring to the drawings, 1 represents a lamp-burner of the type known as the incandescent-mantle burner and common to the present class of lamps; 2, the mixing or commingling tube, in which the supply of combustible vapor and atmospheric air are mixed and carried to the burner to effect an incandescent heating of the mantle thereof,

and 3 a vertical extension or supporting-arm,

forming a permanently-connected part of the supporting frame or harp for the burner.

4 is the supply bowl or tank, containing the supply of gasolene or other like volatile hydrocarbon used in the lamp and which bowl is preferably of the closed type and in which a pressure of air is maintained above the contained supply of fluid' hydrocarbon by means of an air-pump 5 or other like appliance, the purpose being to attain a uniform pressurefeed of such fluid lo the vapor-generator during continued use. In the particular construction illustrated in Fig. l of the drawings such air-pump 5 is shown as extending horizontally across the top of the supply-bowl 4, with the ends of such pump projecting through the walls of the bowl.

6 is thelliquid-hydrocarbon-supply pipe, extending from the supplybowl to the vapor-, 7o generator and provided with the usual stopvalve 7 and needle-regulating valve 8, by means of which the supply to the vapor-generator is regulatedv and controlled.

9 is the vapor-generator, of any usual and suitable form and arrangement and adapted to receive a supply of liquid hydrocarbon from the supply-bowl 4, convert the same into vapor, and discharge it into the mixing or commingling tube 2, by which the mixed air and combustible vapor is conducted to the burner.

2 is an ornamental ball surmounting the top of the tube 2 and which is adapted to partly counterbalance the weight of the font in a hanging-lamp construction.

The construction so far described is usual to and common with the difierent forms of incandescent vapor-lamps now on the market.

The novelty of the present invention con- 0 sists in the means whereby the combined font and vapor-generator as a single part is detachably'secured in operative connection with the lamp frame and burner in a firm and substantial manner. 5

In the construction shown in the drawings as illustrative of the present invention, 10 is a depending projection forming a part of the combined font and vapor-generator and having any suitable shape, preferably that of a [00 cylindrical post, as shown in Fig. 2.

11 is a socket formed in the upper end of the arm 3 and having a shape corresponding with that of the depending projection or post and adapted to receive the same in an engagement of the parts.

The cylindrical shape of the post or projection 10 and the socket 11 thereforis preferred in the present connection in that it affords a convenient and simple means for swinging the vapor-generator 9 laterally out of the way in removing and replacing the chimney or mantle of the burner.

12 is a set-screw adapted to clamp the parts together against accidental engagement or disarrangement with relation to each other.

13 is an expanded collar having perforated walls and adapted to slide upon the jet-head 15 or delivery end of the generator-tube 9, with its forward end provided with a reduced neck 14, which is adapted to engage over' the receiving end of the comminglingtube 2 to maintain the proper alineinent of the parts. With this construction the collar 13 can be moved back on the generator-tube 9 out of its engagement when it is desired to remove the combined font and vapor-generator for refilling and like purposes.

Having thus fully described my said invention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination in a vapor-lamp, of a font and a permanently-attached vaporizer, a harp or frame supporting the burner and provided with a commingling-tube and a supporting-arm, and a detachable connection between the font and the harp consisting of a smooth vertical projection on one part and a smooth vertical socket on the other part to receive said projection, and adapted to afiord means for the ready removal of the font and generator as a whole, substantially as set forth.

2. The combination in a vapor-lamp, of a font and a permanently-attached vaporizer, a harp or frame supporting the burner and comprising a commingling-tuoe and a supporting-arm, and a detachable connection between the font and the harp, consisting of a vertical projection on one part, a vertical socket on the other part to receive said projection, and adapted to ali'ord means for the ready removal of the font and generator as a whole, and a clamping-screw to secure the parts against disengagement, substantially as set forth.

3. The combination in a vapor-lamp, of a font and a permanently-attached vaporizer, a harp or frame supporting the burner and comprising a corniningling-tnbe and a supporting-arm, and a detachable connection between the font and the harp consisting of a vertical'cylindrical post on one part and a vertical socket therefor on the other part, and an expanded and perforated couplingsleeve adapted to couple the vaporizer and the cornmingling-tube in alinement, substantially as set forth.

Signed at Chicago, Illinois, this 23d day of March, 1901.
